Old Tjikko

Old Tjikko is a 9,550 year old Norway Spruce tree, located on Fulufjället Mountain of Dalarna province in Sweden. Old Tjikko is the world’s oldest known living individual clonal tree. However, there are many examples of much older clonal colonies (multiple trees connected by a common root system), such as “Pando”, estimated to be over 80,000 years old. The age of the tree was determined by carbon dating of the root system under the tree, not by dendrochronology, or counting tree rings.
